01Narrative

Silphium brachiatum is a species of flowering plant in the family Asteraceae known commonly as Cumberland rosinweed. It is a rare member of the genus Silphium and is native to the southern Cumberland Plateau where it is found in only a few counties of Alabama, Georgia, and Tennessee. It was described by Augustin Gattinger, the first state botanist of Tennessee.

05DNA & barcodingmolecular

A DNA barcode is a short, standardised stretch of genes that works like a fingerprint — enough to tell one species from another. Below is the molecular trace Silphium brachiatum has left across the world's sequence archives.

06Genome at a glanceCCDB

The complete instruction manual Silphium brachiatum carries — its genome. We read it from three angles — how big it is, how the DNA is packed into chromosomes, and how completely it has been sequenced — and explain how to read each value as you go.

Chromosomes & ploidyhow the DNA is packaged

2n is the full chromosome count in a normal body cell; n is a gamete (egg or sperm), which carries half. Ploidy is how many complete chromosome sets each cell holds — 2× (diploid) is typical for animals, while higher levels (polyploidy) are common in plants.
